Title: Method of controlling speed of main diesel-engine
Inventor: SAKAMOTO NOBUHIKO
IPC: F02D41/08
Filed: 1984-03-19
Abstract: PURPOSE:To improve variations in speed with respect to variations in load of a main engine, to improve the followability upon change of set speeds, to obtain an excellent control performance upon transient and steady state operation, to enhance the control performance as possible as it can, and as well to aim at saving fuel consumption, by carrying out the control of the main engine taking into account of the feature of the dynamic characteristic of the main engine. CONSTITUTION:A compensator 6 calculates a generated torque from a main engine in accordance with the difference between output signals (a, b) from a PI control section 4 and the compensator 6 itself, which is an actuator position instructing signal (b), and multiplies the generated torque by a gain F to obtain a local feed-back signal (c). When set speed is changed, if the generated torque from the main engine which is calculated by the compensator 6 in accordance with the signal (b) is small, the signal (c) is small and therefore the signal (a) is compensated to be slightly reduced so that the signal (b) has a value corresponding to a deviation (d) in speed. On the contrary, the generated torque from the main engine is large, the signal (a) is compensated to be largely reduced, and therefore, the signal (b) has a value very smaller than a signal corresponding to the speed deviation (d). That is, when the torque is small, the amount of fuel injection is increased while, when it is large, the amount of fuel injection is restrained.

CONSTITUTION:Cr, Cu are sequentially laminated on two surfaces of glass substrate to form a conductor film of five layers shown by 4a, 4b, a', 10, and 11. Then it is patterned from upper layer through photoetching method to produce two layers 4a, 4b and an electrode terminal composed of five layers. Thereafter an alumina layer 6 is coated on the discharging electrode 4 to produce a dielectric layer. Then a frame 7 of encapsulation material is printed at predetermined position on the glass substrate and burnt. Furthermore a surface layer of MgO is formed on the surface of alumina layer 6 and two of said substrates are faced each other to obtain a panel. Finally the upper layers 10, 11 at the end of five layer electrode is removed through etching. Consequently the oxcidation of electrode during assembling is prevented resulting in the improvement of process efficiency.

IPC: E03F5/10
Filed: 1994-02-14
Abstract: PURPOSE:To prevent propagation of mosquitoes by furnishing an insect screen on a rainwater basin. CONSTITUTION:An insect screen 6 is pinched by the lid 3 of a rainwater basin and its body 4, and reinforcing is made with a plastic tape and heat processing or adhesive in order to increase the strength of the netting at the peripheral part 11 of the screen 6. Mosquito propagation requires an egg-laying place such as a water sump, growing environment for mosquito larvae, and a moving path for mother mosquito for laying eggs, and propagation can be precluded by shutting the moving path between the inside and outside of the body 4 of rainwater basin using this insect screen 6. A path via drain pipes 5A, 5B is comparatively long and is of minor importance as a moving path for mosquito, but this plays a role to prevent fallen leaves, earth and sand, etc., from intruding into the basin body 4.
